Guardians of the Galaxy Vol 2: More about Nathan Fillion, Miley Cyrus' cameos

As the days pass by until the release of Guardians Of The Galaxy Vol 2 , it's becoming something of a minefield of rumours and confirmed secrets out there, and avoiding spoilers around the plot is difficult, to say the least.

But if you're one of those fans who actually enjoys spoilers, it's a wonderful time to be alive, as the director and people who've seen the film are gleefully releasing as much information as they can.

After Firefly star Nathan Fillion posted a mysterious image on his Instagram account, Marvel fans went crazy assuming he has a cameo in sequel as Simon Williams — also known as Wonder Man — but his caption suggested that his role was cut from the film.

According to an official Twitter posting from lifestyle blogger Sarah Ruhlman, pop star Miley Cyrus will be lending her vocal talents to Guardians of the Galaxy Vol. 2 by way of playing original Marvel Comics character Mainframe.

As comics fans may already know, Mainframe is an alternate universe version of Vision from The Avengers who operates within the same fictive space as Peter Quill (Chris Pratt) and company — though how the character will be adapted to suit the purposes of the MCU remains to be seen.
